<h1 class="topictitle1">Failed to Perform a Backup or Restoration Job Due to Insufficient Memory of SAP HANA</h1>
<div><div class="section"><h4 class="sectiontitle">Symptom</h4><p>The backup or restoration job fails. Check whether the OOM log file generated at the job time point exists in the <em>SAP HANA installation directory</em><strong>/trace</strong> directory. If it exists, memory overflow occurs.</p>
<p>The log file name is as follows:</p>
<p>preprocessor_hana1.30002.rtedump.20240117-021229.018590.oom.trc</p>
</div>
<div class="section"><h4 class="sectiontitle">Possible Cause</h4><p>The backup or restoration operation fails because memory overflow occurs in the production environment.</p>
</div>
<div class="section"><h4 class="sectiontitle">Procedure</h4><p>Ensure that the remaining memory is greater than 10 GB after the SAP HANA production environment is installed.</p>
<p>To check the remaining memory in the production environment, perform the following steps:</p>
<ol><li><span>Use PuTTY to log in to the database host.</span></li><li><span>Run the following command to check the remaining memory in the production environment:</span><p><pre class="screen">free -h</pre>
<p>The command output is as follows, indicating that the remaining memory in the production environment is 11 GB.</p>
